ABSTRACT:
An image drawing apparatus includes a first data reading unit which stores a source image data into a first image data buffer. A second data reading unit reads a destination image data from a destination area of a memory device and stores the destination image data into a second image data buffer. A third data reading unit reads a transmission coefficient data from the memory device and stores the transmission coefficient data into a transmission coefficient data buffer. A transmission drawing processing control unit executes a transmission drawing processing for the source image data and the destination image data by using the transmission coefficient data to generate a processed image data. The transmission coefficient data has a block size that is the same as a block size of the source image data, and contains transmission coefficients that are varied with respect to every pixel of the source image data.
